Fontana Aviation Touchless Faucets — Retrofit Practicality & TCO

Retrofit Practicality for Existing Monuments

Drop-in geometries and adaptable kits

The assemblies are dimensioned to align with typical lavatory cutouts and standoff patterns so that legacy faucets can be replaced with minimal or no monument rework. Adaptable deck- and wall-mount kits accommodate common panel thicknesses and composite stacks, preserving the structural integrity of existing monuments and avoiding new penetrations.

Service access within line-check windows

Front-serviceable aerators and under-deck quick-connects for water and low-voltage power enable rapid swaps or inspections without removing monument panels. In many lav variants, an under-1-hour change-out is realistic during line-check windows, keeping aircraft on schedule and avoiding deferred-item churn.

Connector discipline to reduce mis-mate risk

Aviation-style locking or keyed connectors with positive latching and clear polarization reduce mis-mating during hurried turnarounds. This makes it easier to maintain the signal integrity during vibration and troubleshooting because of the standardized harness interfaces.

Total Cost of Ownership (TCO) Logic

Fewer nuisance triggers = Fewer write-ups

Detection windows that are more stable (such as “Time of Flight”) reduce instances of spurious detection and “hand hunting.” Increased predictability in tight cabins is primarily beneficial to passengers.

Lower water use → weight and waste savings

Flow controls in the ~0.35–0.5 gpm range, combined with tight dwell-time logic, curb potable consumption and gray-water generation. Over large fleets, the mass reduction compounds into fuel and service-cycle savings and supports airline sustainability targets.

Ruggedized electronics → higher MTBF in harsh cabins

Conformal-coated, vibration-resistant electronics packaged for humidity excursions and pressure changes extend mean-time-between-failures in high-vibration, high-humidity spaces typical of lavatory zones. Packaging emphasizes strain-relieved harnessing and ingress control.

Common platform → simpler spares and training

A shared mechanical and electrical platform across variants reduces SKUs, streamlines technician training, and eases stocking decisions. Consistent service procedures shorten hands-on time and improve reliability across mixed narrow- and wide-body fleets.
